Lucky and Christi, two female reindeer, are making a guest appearance at the zoo for all six weeks of WildLights presented by KeyBank, the zoo's all new winter lights festival, opening tonight, Nov. 23.

And with nine other famous reindeer on your minds this holiday season, it’s only appropriate to honor each of them with nine fascinating facts about these sleigh-pulling beauties.

1. Reindeer are also known as caribou in North America. Though, many use “reindeer” to describe domesticated caribou.

2. Different species of caribou live throughout subarctic regions of Europe, Asia and North America. In the U.S., caribou inhabit the northern-most territories of the states and roam throughout all ten Canadian provinces. However, their populations are dwindling. Today, caribou are severely endangered in the Northwest.

3. It is the only deer species in which both the ladies and the gents grow antlers. Every year, reindeer shed their antlers and grow a new pair. The males shed in the winter, but the females won’t shed theirs until after they give birth in the spring.

4. Although reindeer can’t fly, they can run at speeds up to nearly 50 miles per hour! And they’re great swimmers, clocking in at 6 miles per hour.

5. Typically, reindeer are herbivores and will eat around 12 pounds of food a day. Unlike other deer, reindeer rely on lichens, or fungus, during the coldest months. Lichen withstands freezing temperatures and fuels reindeer with carbohydrates that will keep them trekking for miles on a full stomach.

6. Using their antlers, reindeer shovel through snow and chisel frozen ground to find food.

7. Reindeer live in herds. Most reindeer will travel among a group of two to five reindeer.

8. People have relied on reindeer for thousands of years. In some cultures, reindeer were fully domesticated and kept for milk and transportation.

9. The image of Santa’s sleigh being pulled by flying reindeer first appeared in American popular culture in the early 1800s.
